I have a Landrover Freelander TD4 2002 - 70K miles. At the weekend car started to emit large amounts of blue smoke from the exhaust. Went under the bonnet to find oil all over hosing. Initially told that this was likely to be blown turbo (very expensive) - but just taken car to local garage who have diagnosed a blocked engine breather unit, which has forced oil back into the engine and led to above symptons. I have just driven the vehicle home. No more blue smoke and all appears well - though may be a little sluggish (may be due to me driving particularly carefully!!). Is the above a feasible explanation of the defect - or could this just be a temporary solution masking a major defect?. I have absolutely no knowledge of car engines (my wallet does - and it breathed a sigh of relief when it wasn't the turbo)
